When rounding a number to the nearest whole number, you look at the digit to the right of the decimal point. If that digit is 5 or greater, you round up; if it is 4 or less, you round down. In this case, 40 is already a whole number, so it does not need to be rounded.
x + (-12) = 28 So x = 28 + 12 = 40
40
Since the quiz/test (or whatever it may be) is out of '40' we know that 40 out of 40 is 100%, or the full marks. Now, since we know that, we can divide 28 by 40. 28/40 = 0.7 After, we take this number and multiply it by 100 to make it equal to the percentage.. 0.7 x 100 = 70 So, 28 out of 40 is equal to 70%
28% of 40= 28% * 40= 0.28 * 40= 11.2
When 40 is decreased by 30% the result is 28.
70 / 0.4 = 175 Therefore, 70 is 40 percent of 175.
It is: 28/40 times 100 = 70%
28 is such a number.
